// not compile (on supported platforms) unless the variable has a constant
// initializer. This is useful for variables with static and thread storage
// duration, because it guarantees that they will not suffer from the so-called
// "static init order fiasco".
// "static init order fiasco". Prefer to put this attribute on the most visible
// declaration of the variable, if there's more than one, because code that
// accesses the variable can then use the attribute for optimization.
//
// Example:
//
// ABSL_CONST_INIT static MyType my_var = MakeMyType(...);
// class MyClass {
// public:
// ABSL_CONST_INIT static MyType my_var;
// };
//
// MyType MyClass::my_var = MakeMyType(...);
//
// Note that this attribute is redundant if the variable is declared constexpr.
